TL;DR: Simple and mild methods for the synthesis of allenes, employing indium- and zinc-mediated dehalogenation reactions of vicinal dihalides in an aqueous solvent, are described.
Abstract: Simple and mild methods for the synthesis of allenes, employing indium- and zinc-mediated dehalogenation reactions of vicinal dihalides in an aqueous solvent, are described. By using these procedures, various allenylmethyl aryl ethers and monosubstituted allenes have been prepared in good to excellent yields.

TL;DR: Zinc is the 24th most abundant element in the Earth's crust and has been widely used as a catalysts in the last three decades as mentioned in this paper ; however, the main application of zinc metal is as materials.
Abstract: Zinc is the 24th most abundant element in the Earth’s crust. Since the discovery of pure zinc metal in the 18th century, the main application of zinc metal is as materials. Because zinc salts are abundant, cheap, non-toxic, and exhibit environmentally benign properties, organic chemists have been interested in using zinc salts as catalysts in organic synthesis during the last three decades. Within this review, we have summarized the progress on applications of zinc salts in organic reactions. Our the target is to emphasize the special properties of zinc catalysts, and further promote the interest of organic chemists.

TL;DR: Organoselenium-catalyzed oxidative deoximations afforded ketones and aldehydes under mild conditions as mentioned in this paper, leading to a waste-free and metal-free deprotection protocol for carbonyl protection strategies.
Abstract: Organoselenium-catalyzed oxidative deoximations afforded ketones and aldehydes under mild conditions. The reactions employ hydrogen peroxide and air as clean oxidants and lead to a waste-free and metal-free deprotection protocol for carbonyl protection strategies as well as the green synthesis of ketones and aldehydes. The mechanisms of this interesting organoselenium-catalyzed reaction have been investigated by control experiments as well as the selenium 77 nuclear magnetic resonance (77Se NMR) tests. This novel reaction largely expands the application scope of organoselenium catalysis.

TL;DR: This method enables generation of CF3-bearing all-carbon quaternary stereocenters by engaging in ruthenium catalyzed reductive couplings with paraformaldehyde to form products of hydrohydroxymethylation as single regioisomers.

TL;DR: In this article, a series of carbazolyl cyanobenzene (CCB)-based organic photocatalysts with a broad range of photoredox capabilities were designed and synthesized, allowing precise control of the reactivity for the controllable reduction of aryl halides via a metal-free process.
